New-driver rules in Idaho
Idaho teens can start at 14½ with a driver training permit, which becomes a supervised instruction permit (SIP) once an approved driver ed course (required for anyone under 17) is completed. The SIP requires a minimum 6-month, violation-free supervised period with at least 50 hours of practice driving (10 at night) alongside a licensed adult 21 or older in the front seat; a traffic conviction cancels the permit and restarts the 6 months. Once licensed, drivers under 16 may drive solo only during daylight hours (defined as 5:00 a.m. to 10:00 p.m.), and drivers under 17 are limited for their first 6 months to one passenger under 17 unless the passengers are relatives.
